Release note 1.4.3:

1. 添加内置存储上传文件文件名有效性检查。
2. 接受好友请求通知的发送者改成接受者发送。
3. 对象存储添加预留类型供扩展使用。
4. 同步专业版数据库表格式。
5. 解决server sdk有轻微内存泄漏的问题。

附件的版本有3种格式，分别是Java通用版本、Deb格式安装包和Rpm格式安装包包，可以根据平台或者自己的习惯下载其中一种软件包。另外在Github也可以下载。也可以下载我们网站上的最新版本，通用Java包，deb格式安装包和rpm格式安装包。 *** 0.42 版本增加了群成员数限制，默认为2000。如果您想修改默认值，可以在升级版本之后，修改t_setting表，把默认的大小改为您期望的。另外修改t_group表，把已经存在的群组max_member_count改成您期望的，然后重启。*** *** 0.46和0.47版本升级到0.48及以后版本时，可能会提示flyway migrate 38错误，请执行 修复脚本 进行修复。0.46和0.47版本之外的版本不会出现此问题。*** *** 0.50版本添加了是否允许客户端发送群操作通知的配置。如果您在客户端自定义群通知，需要在服务器端配置允许，没有使用自定义群操作通知的不受影响。*** *** 从0.54之前版本升级到0.54及以后版本时，会提示flyway migrate错误。因为0.54版本删除了sql脚本中默认敏感词的内容，flyway checksum失败。请执行update flyway_schema_history set checksum = 0 where script = 'V17__add_default_sensitive_word.sql';来修复。*** *** 从0.59之前的版本升级到之后的版本执行数据库升级时间比较长，请耐心等待提示运行成功，避免中途中断。 *** *** 0.62/0.63 版本有严重的问题，请使用0.64及以后版本，或者0.61版。 *** *** 从0.68 版本起添加了pc在线是否默认手机接收推送的开关，默认为开，与以前版本作用相反，请注意兼容（可以关掉与之前保持一致或者升级客户端） *** *** 从0.78 版本起把MySQL数据库中关键字都改为大小写敏感，另外生成id的方法也做了改变，只生成小写的id，避免出现id重复的问题，建议所有客户都升级 *** *** 从0.79 版本起把log4j升级到log4j2，因为log4j已经不再维护而且还有已知的漏洞，建议所有客户都升级，升级时注意更新log4j2的配置文件 *** *** 0.97版本更改了启动脚本wildfirechat.sh，如果是升级服务，请注意更新启动脚本。*** *** 1.3.8版本添加了server api发送消息的限制，限制消息体最大内容不能超过64KB，如果升级请注意业务系统发送消息大小。***
